I just bought 6 new Dells for my office, all of which have the ICH5 southbridge (the non-RAID version). I reformatted over all the Dell-installed software crap and loaded fresh copies of XP. I downloaded and installed the newest Intel INF drivers for them, but Intel Application Accelerator refuses to install, saying that the hardware is incompatible. This appears to be because the last released version was all the way back in November of 2002, which was long before the ICH5 was even released.
I have always thought that the INF utility was mainly for Intel Northbridges and that Application Accelerator was for the Southbridges. So I dissected the Intel INF drivers and discovered that the INF Utility actually covers components on both chips (all MCH components, and the LPC, USB, SMBus, and Ultra ATA controller components on the ICH).
My question is: if the INF Utility seeminly covers everything, what do I need Application Accelerator for, and why have they released new versions of it for the ICH5R, but not updated the non-RAID version to cover the ICH5 Standard?
